Abstract - The work deals with minimization of dust
particles on Roadside by designing a portable highway wind
turbine. The particulate matters which are present on
roadside gets subtended in air by the motion of vehicles. This
directly affect the riders or drivers vehicle handling capacity.
So the idea is to take energy from the pressure column created
by the automobiles while passing through the highways and
expressways. The pressure column is due to high and low
pressure energy band created by the motion of automobiles.
Wind flows by the virtue of this pressure difference,thiswindis
sufficient to generate electricity which can run a vacuum
pump. A pump starts suction periodically and removes the
dust from the road.
Wind works as a primary source of energy for the system
consists of a Vertical axis wind turbine.
Key Words: Wind Energy, Vertical axis wind turbine,
Vacuum pump, Dust cleaning…
1.INTRODUCTION
As air pollution is becoming a major threat for the society
thus we aim towards eradicating this threat with the help of
a renewable source of energy. The dust particles present on
the roads are danger to the road safety. The motivation of
this project comes from the Swachha Bharat Abhiyan, a
scheme of central govt. of India for pollution free
environment. We can eradicate this problem by applying
manual man power or any other non-renewable technology,
which can be costly. Therefore, to suppress this problem we
initiate a project which uses a renewable source of energy
i.e. wind energy. The wind energy is a fastest growing, eco
source of energy which is reliable and inexpensive energy
source.
The problem arises due to the presence of the dust particles
on roads are:
Visibility; the dust particles present on the road, when
mixes with the fog and forms smog, this decreases the
visibility on the road, which results in mishandling and fatal
accidents.
Vehicle handling; the contact betweentheroadsurfaceand
the surface of tyre reduces due to the presence of dust
particle layer between them, during the braking and turning
of the vehicle, it causes the problem like skidding.
Road safety; foreign dust particles when entering in the
eyes of the driver or the rider causes discomfort and
irritation which is a critical problem when driving or riding
on a busy road.
As these problems are fatal and life threatening, we design
an idea to solve this problem by employing the vacuum
pumps on the roadside powered by vertical axis wind
turbine. The VAWT is designed in such a way that it's blades
are positioned vertically towards the axis of rotation so
bladeswill always rotate in the same direction regardlessof
the direction of the wind flow. The wind is generated by the
motion of the vehicles on the highways which is always
destined to remain in one direction.
The concept of wind generation by the vehicle's motion is as
shown in the figure

2.1.1 Turbine
We are implementing the vertical axis wind turbine whose
blades will rotate about the axis of the turbine. To overcome
from the stationary inertial force of the wind turbine is a
major challenge hence to overcome this it is suggested that
the pitch angleof the turbine shouldnot be 90degree,forself
starting.
Fig 2.1: VAWT set-up
2.1.2 Dynamo
Dynamo is employed to convert the rotational energy of the
turbine blades into the electrical energy. When the central
shaft of the turbine rotates by the rotation of the blades, the
central shaftof the turbine is connectedwith thedrivenshaft
of the dynamo by the belt and pulley arrangement. The
electrical energy generated by the dynamometer is supplied
to the electrical storage unit.
Fig 2.2 : Dynamometer used in project
2.1.2 Electrical Battery
The electrical energy generated by the dynamo is stored in
the battery, the energy stored in the battery can be further
used to run different components. There are different
electrical components attached to the battery which act as a
charge controller to prevent damage to the battery.
2.1.3 Vacuum pump
To accomplish the desired objective of our project we are
using an electrically powered vacuum pump. The dust
particlespresent on the roadside are sucked by the pressure
difference created by the vacuum pump. This vacuum pump
is driven periodically by using the electrical energy storedin
the battery.

2.2 Design Calculations
Power of wind is directly proportional to the density of air,
area of segment and the cube of natural wind speed. the
power equation of wind is given by;
Pw= 1/2 ρAv3
Pw= power of wind
ρ= air density
A= area of blade
v= velocity of wind
At standard temperature and pressure (STP= 273K and
101.3KPa)
Pw=0.647Av3
Mechanical power that can be obtained from wind with an
ideal turbine
Pm=1/2 ρ(16/27 v3)
Energy which we have to produce 20hrs a day
E=17000 (Battery=16200J)
Let us assume to pass 100 vehicles with a speed of 60 to
70kmph wind generated by this is 4.5 m/s for at least 4 sec
per vehicle.
We want to charge Battery for 20 hrs
Available energy = 20*100*4
= 8000sec

3. Implementation on the Highways
The moving vehicles may be all types i.e. light or heavy
running on road such as two, four wheelers and even bigger
vehicles, when these vehicles move across the divider in
opposite direction they will generate a pressure difference
which results in the flow of wind at a high velocity. When
these high velocity wind strikes on the designed blade, this
will cause them to rotate which results in the rotation of the
central shaft of the turbine, the central shaft of the turbine
connects with the pulley which acts as a driving member.
Thus, the rotational energy of this system runs the dynamo
which generates the electrical energy.
Now the generated electrical energy is stored in the battery,
the continuous supply of energy can cause a problem of
overcharging so by using the electrical controllers, we
prevent our battery from overcharging. If wind is properly
directed towards the wind turbine blades, optimum
electricity may be generated.
A vacuum pump is employed on the base of the divider, to
remove the dust particles from the roads.
The pump is driven by the electrical energy supplied by the
battery periodically. There are different filters provided on
the pump which will prevent the pump from suction of
larger and unwanted particles such as polythenes, stones
and metal pieces etc. Since these particles may harm the
pump and ultimately reduce the efficiency of the system.

4. Result & Conclusions
4.1 Result
The results are taken, when implementing the project on
highway so when vehiclespasson road this causerotationin
blades of turbines. The energy generated from system is
sufficiently used to drive vacuum pump. The dust particles
are easily cleaned from roads.
4.2 Conclusion
Conclusively, different data iscollected by implementingthe
system on roads. Using the data it is clear that we havetouse
more than one system within some distances. When the
number of system increased on highwaysit will abletodrive
vacuum pumps. Collective of turbines on a long strip of
highwayshas a potential to generate large amount ofenergy
that can be used to drive pumps, street lights and other
applications. The generated power stored in battery is
sufficient to drive more than one vacuum pumps. High
capacity Vacuum pumps should be employed to get
satisfactory results on roadside. The design of system is
sustainable and environmental friendly.
Cleaning of road will be in periodical manner, when the
traffic will be low, vacuum pumpswill start cleaningandwill
continue till some minutes. The time duration of pumps will
depend on their the suction capacity.
According to our practical observation on roads and traffic
density, the time for cleaning dust should be four times in a
day. This should be started on 6AM then 11AM, 4PM and
8PM respectively. This time also dependsupon thepollution
level of dust particles and surrounding atmospheric
conditions such as velocity of wind etc.
Hence, the system is reliable and effective on highways
where the problem of dust particles is a serious concern.
This project needs onetime investment and proper
designing. During the setup proper guidance and
observation is needed which increases the efficiency of the
system.
